British hip hop collective Roll Deep have been widely endorsed â from ‘Fiddy’ Cent to Tate Modern, where they contributed a sound art installation last year.

Despite acclaim for their 2005 album In At The Deep End, they were unceremoniously ditched by their label; this resolutely lo-fi follow-up yields mixed results on 18 tracks.

Plus points include an urgent rabble of vocals from MCs including Jammer, Manga and Frisco (a punchy combination on Ride Or Die Chick).

Earnest tracks such as Badman sound bleakly timely. On the flipside, although production credits include Wiley, Danny Weed and Target, some of these backing tracks sound weedy.

There are cheeky highlights â the pop cult humour infusing tracks such as Flame Grilled Whopper and bass-heavy anthem Roll Deep Regular â but rather than a crew at the top of their game, this sounds like a recovery period.
